Abstract

The present invention concerns a new acid trisazo dye suited for the dyeing of natural and synthetic polyamidic fibres and particularly for the dyeing of leather. The dye has the following structural formula: <IMAGE> (I) <IMAGE> and dyes in a full black shade. The present invention also includes a process for the preparation of dye (I) and comprises tetrazotizing 4-4' diaminoazobenzene and then coupling the tetrazo-compound thus formed with 2 molecules of 2-carboxymethylamino-8-naphtol-6-sulphonic acid (carboxy methyl-gamma acid) in an alkaline medium.
